Capt Pit Bull ( hope this is not a CRM nickname )

You are absolutely right. Your remarks make a lot of sense and indeed the emphasis should be on not to manoeuvre against a RA. Good point .
Now how do we get this idea to progress further ?

On your second remark , about visual aquisition, I can support your comment but cannot forget the fact we discovered while examining the TU154 FDR : the a/c turned towards the 757 and was still doing 1900 ft/min when it collided.
The awsome fact , in that collision, is that if the TU154 crew did not see the 757 , it possibly had stayed on course, and had passed well ahead of the 757, ( but this is speculation ) but more importantly, it would most probably have levelled off at FL350 , therefore would have reduced its rate prior to that, passing definitively above the 757.
Depending on how you look at the geometry, had the TU 154 been between 2 and 4m higher they would have missed each other.
It is not easy to find a procedure covering 100% of cases.
